With the Ravens preparing for their first playoff game in four years against the Los Angeles Chargers on Sunday, I’ve offered a dozen thoughts, each in 50 words or less:

1. The 68-yard touchdown highlighted a career passing day for Lamar Jackson in Week 16, but he also made some good decisions on check-downs and short throws in the first half. He’ll need more of that to offset the Chargers’ pass rush the second time around.

2. No matter what happens, the 21-year-oldgaining playoff experience as a rookie is invaluable — and exciting — for the future. Joe Flacco posted a 50.8 passer rating with one touchdown and three interceptions in his first postseason run before eventually becoming “January Joe.” Be sure to keep that perspective.

3. Taking nothing away from the Ravens’ dominant defensive performance, seven of the eight Chargers penalties were committed by the offense with a few wiping out big gains and stalling any momentum for Philip Rivers. Like in Week 16, Clete Blakeman will be Sunday’s referee.

4. Za’Darius Smith will again be a key figure trying to exploit an underwhelming interior offensive line. The pending free agent has positioned himself for quite a payday with 8 1/2 sacks. Following up what he did in the first meeting against the Chargers — 1 1/2 sacks — will only strengthen that.

5. Los Angeles would be wise to spread the Ravens defense out more frequently and throw to running backs on the perimeter to try to offset the pass rush that made Rivers miserable. Chargers running backs did Rivers no favors in pass protection the first time around anyway.

6. Baltimore isn’t trending in the right direction in the red zone and on third down the last two weeks, going 1-for-7 and 7-for-27 in those respective categories. You can only expect other areas of the game to overcome those deficiencies for so long without substantial improvement.

7. How the Chargers fare against this running game the second time around will be fascinating, but the absences of linebacker Jatavis Brown and nose tackle Brandon Mebane loom large. You never want to test your depth against a rushing attack known for wearing down its opposition.

8. Mark Andrews led all rookie tight ends in receiving yards, yards per catch, yards after the catch, and first-down receptions, per Pro Football Focus. The third-round pick’s emergence as a big-play threat and reliable target has been critical when Jackson has needed to throw.

9. Only 12 players on the current roster were in the organization the last time the Ravens appeared in the playoffs four years ago, but Jimmy Smith was on injured reserve then and Flacco is now the backup quarterback. Things sure change quickly, don’t they?

10. Speaking of Flacco, his comment admitting the backup job is “not the most fun position in the world” predictably drew criticism from the same folks who’d likely bash him for not being a competitor if he said he enjoyed his new role. I won’t miss this kind of nonsensical criticism.

11. Justin Tucker was an AP first-team All-Pro selection while Marshal Yanda and C.J. Mosley were second team. Reporters receive much criticism — some deserved — for awards and Hall of Fame voting, but players, coaches, and fans are the ones voting for the Pro Bowl that again excluded the NFL’s best kicker.

12. Whether the Ravens advance or not, you just know Kansas City and New England coaches have spent more time on their bye week preparing for Baltimore’s rushing attack than for any other AFC team playing this weekend. It’s a scary matchup for anyone.
